The Cadillac: The Bed That Became a Stage
It began as a reinforced table strapped with springs, built for the bodies the Reformer couldn't fix. Seventy years later it's the most photographed apparatus in any Pilates studio — and probably the least understood.
Anyone walking into a Pilates studio for the first time pauses for a second in front of the Cadillac. It has the scale of an impossible piece of furniture: a canopy-shaped metal frame, horizontal bars, a cluster of springs hanging from the top rail, foot straps suspended in mid-air. It looks like nothing else in a conventional gym. And yet its lineage is the humblest of all the method’s equipment: it began, quite literally, as a bed.
We’ve told that origin story in these pages before: at the Knockaloe internment camp during the First World War, Joseph Pilates tied springs to infirmary bedframes so that bedridden internees could exercise. Over the years, that single gesture split into two distinct pieces of equipment. One flattened out into the Reformer, the sliding carriage that defines any group class today. The other kept the vertical, canopy-bed structure, and eventually became the Cadillac.
At the studio on Eighth Avenue in New York, Pilates called his early versions the “Massage Table” or “Rehabilitation Table”: reinforced massage tables fitted with a metal frame from which springs and bars hung. He reserved them, according to a historical reconstruction by Pilates instructor and historian Reiner Grootenhuis — who in 2018 published the first public manual on the apparatus, first in German and later in English — for his most difficult clients: bodies that couldn’t start on their feet, spines that needed traction before resistance. It wasn’t the apparatus a class opened with. It was the one brought out when the Reformer wasn’t enough.
The Name
Like almost everything around Joseph Pilates, the legend behind the name has more than one version and no document to settle it for good. The one told by Romana Kryzanowska — his closest student from the 1940s onward — is the one that stuck: a client, seeing the gleaming metal structure with its pulleys and levers, asked if that was his new Cadillac. The car brand, then a byword for luxury and status, attached itself to the apparatus as an affectionate nickname. There’s no receipt, no letter, no exact date to confirm it; there’s an anecdote passed from student to student, and it’s worth treating it as exactly that.
What can be traced with more certainty is its physical evolution. Photographs of the Pilates studio from the mid-twentieth century already show a recognizable Cadillac — push-through bar, spring-loaded trapeze hanging from the top frame, foot straps — installed alongside the row of Reformers, not tucked away in a separate room. It had stopped being the exception and become a fixture of the cast.

From Exception to Centerpiece
What’s curious is that hierarchy has flipped. In a boutique studio today, the Cadillac is rarely the daily workhorse — that role belongs to the Reformer, which packs more bodies per square foot and sustains the group-class model that makes a studio profitable (something we cover elsewhere in this section). The Cadillac, meanwhile, has become the apparatus of private sessions, post-surgical rehab, pregnancy, the body that needs to be supported before it can be challenged — exactly the function Pilates built it for a century ago, back when it didn’t yet have a name.
It’s also become, without anyone planning it, the most photogenic piece of equipment in the room. Hanging from the trapeze, working in suspension with feet in the straps, letting the spring bar hold the body’s weight in the air: these are gestures that read as dance on social media and as joint offloading in a rehab room. It’s the same movement seen from two different places, and that double reading — therapeutic and theatrical — is perhaps the truest inheritance of the method’s original spirit: an apparatus built to hold up a body that can’t, equally capable of challenging a body that can do plenty more.
Scaled-down versions of the Cadillac — the Tower, wall-mounted, without the full frame — now let studios offer part of that repertoire without giving up floor space. It’s a practical answer to a profitability problem. But it’s worth remembering that the piece it descends from is still, in essence, the same bed strapped with springs that a man locked away on an island turned into a promise of movement.
